This technical information has been contributed byGREENVILLE, S.C.—A new electronic component from Kemet Corporation is reported to be the first polymer electrolytic capacitor to meet all of the requirements of the Automotive Electronics Council’s AEC-Q200 specification for passive components. Kemet’s T598 High Humidity/High Temperature Series, KO-CAP®, is an AEC-Q2000 qualified polymer electrolytic capacitor that offers “stability and endurance in extreme humidity and temperature environments,” according to a release from the company.
Polymer Electrolytic Capacitor is Reported to be an 'Industry First'
Kemet’s new AEC-Q200 qualified T598 KO-CAP® polymer electrolytic capacitor is said to deliver stability and endurance in extreme humidity and temperature environments.
Kemet reportedly built on the success of its T591 Series, further refining the design, materials, and manufacturing to ensure that the T598 Series delivers higher stability and endurance under harsh conditions. The improvements are said to result in a design that exceeds the humidity bias testing requirements of 85 degrees Celsius with 85 percent relative humidity, in addition to delivering stable electrical performance at 125 degrees Celsius.
“In 1999, KO-CAP offered engineers a breakthrough in high capacitance, low ESR and long lifetime capacitors,” said KEMET Senior Vice President and Chief Technology Officer, Dr. Philip Lessner, in a statement. “Since this time, designers have utilized polymer electrolytic capacitors in space-constrained or high performance applications. Now that KO-CAPs meet all of the AEC-Q200 requirements, engineers can incorporate these innovative capacitors into automotive and other harsh environment applications.”
The T598 Series is available in capacitances of up to 330 microfarads and rated voltages up to 16 volts. The qualification test plan is in accordance with AEC-Q200, and these products are manufactured in an ISO TS 16949 certified facility. This series is available for Production Part Approval Process (PPAP), Part Submission Warrant (PSW), and Change Control Notification.
Typical applications include decoupling and filtering of DC-to-DC converters in automotive infotainment and advanced driver assistance, as well as industrial and telecom applications where harsh conditions, such as high humidity and temperature, are of concern.
